Forever-young physicist Freeman Dyson, now 83, has long been beloved by scifi writers for his extremely fucking cool ideas. He invented the Dyson Sphere, featured in a Star Trek: TNG episode, where the crew visits a sun wrapped entirely in an artificial sphere that captures every bit of solar energy available (you can see a Dyson Ring in Halo). Now Dyson is battling it out with neo-Luddite Wendell Berry in the NY Times Book Review. Read the old crank getting crankier![NYBOB]
